'do all whom it may concern:

v 1 Be 1t known that I, \Vmrrnn l. bol-uu-nnnn,

of Baltimore, in the State of Maryland, have It is necessary that fuels which are to be used in aeroplane motors shall have great dependability. inasmuch any uncertainty in the operation of the aeroplane, by reason of variability in the character of the fuel or failure of the fuel to perform its intended work, may bring about disastrous consequences.

For this reason, it is desirable to avoid using in such fuels large percentages of petroleum products, inasmuch as commercialpetroleum products do not ordinarily have a constant composition, and are usually comprised of varying quantities of a number of different constituents.

It is, therefore, the object of my invention to provide an aeroplane fuel avoiding these disadvantages and taking into account the circumstances above referred to.

' Still a further object of my invention is to provide fuels of the above character by the use of benzol, and the constituents of which are 'chosenin such a manner to obviate any tendency of the benzol to crystallize out at the range of atmospheric temperatures to which aeroplane motors are subjected at the varying altitudes in whichaeroplanes operate.

Further objects of my invention will appear from the detailed description thereof contained hereinafter.

While my invention is capable of being carried out in different ways, for the pnrpose of illustration l shall describe only certain ways of carrying out the same herein.

Specification of Letters Patent.

Patented Nov. 3.9211.

Application filed June 25, 1918. Serial No. 241,785.

For example, a fuel made in accordance with my invention may be comprised of:

40 parts by volume of ethyl alcohol,

parts by volume of benzol,

30 parts by volume of ethyl ether.

The percentages of the above constituents may vary to some extent, if desired. F or example, the alcohol may vary from to 50%, the benzol may vary from 25 to and the ether may vary from 20 to although I have obtained the best results by the specific composition above given.

The ethyl alcohol in the above composi tion may be the ordinary alcohol having a strength of 95%,but I may, if desired, use an alcohol having a greater strengtl'i, or even absolute alcohol.

By the use of the ether I avoid the necessity of using alcohol having a greater strength than 95%, as the ether itself will prevent the benzol from crystallizing out at very low tem mratures.

Instead of the ethyl alcohol,however, I may use methyl alcolipl or butyl alcohol, and instead of the benaol I may use toluol, and instead of the ethyl ether I may use butyl ether.

Aeroplane fuels made in the manner described above can be used with greatest reliability in the operation of aeroplanes, notwithstanding the varied atmospheric conditions to which aeroplane motors are subjected.

Neverthelessall of these fuels are of such anature that they may be readily used in internal combustion engines generally, whether used for operating aeroplanes or not. v

While I have described my invention above in detail, I 'wish it to be nnderstood that many changes may be made therein without departing fromthespirit thereof.

I claim:

A fuel comprising from 35% to of ethyl alcohol, from 25% to 35% of benzol, and from 20% to 40% of ethyl ether.

In testimony that I claim the foregoing l have hereunto set my hand.
